There was a bug when the new Eudaemon UI first came out that some people who had more than 5 of each Eudaemon ended up losing them. So, COSMOS warned people about the bug. He didn’t tell anyone to sell all but 1 ‘mon. It is easy to have 4 or 5 of each of the Eudaemon Shard ‘mons at all times. So selling 1 occasionally shouldn’t be a hardship.
